I see that you are a huge fan of Killer Bee.
Well alrighty but here is something you should know.
There are at least 3 members that he would lose, or has already lost to. (4 if you count Tobi)
So what chance does he have against beating people who have already beaten him when you are adding in other people who can beat him, and like 6 people who would at least be a challenge for him?
I'll tell you. He has no chance. 0% A toddler with a stick has more chance of beating up Mike Tyson then Bee has against all of Akatsuki at once.
